It was equally useful for camouflage and as a windproof garment that provided a method of carrying ammunition or equipment.

German parachutist's Knochensack ("bone sack"). This first "smock" was designed to be stepped into and pulled up over the body like a set of overalls which had had the legs removed from mid-thigh.
The new Denison smock was put on and removed by pulling over the head: the collar zipped open as far as the chest, making it a true
smock style. The zip was covered by a cloth flap, which had no buttons or other method to fasten it down. Introduced in 1942, the "Airborne Smock Denison Camouflage" bore a camouflage pattern designed by a

, with a sleeveless green denim oversmock being worn over the ensemble to prevent
rigging lines snagging in the webbing and causing a 'chute malfunction. This sleeveless smock had a long external zip (often removed and used to make the half-zip Denisons full zip), a monkey tail that press studded to the outside front of the oversmock and two elasticated open pockets on the lower front which were to hold grenades for use whilst in the air or immediately upon landing. After a successful parachute landing fall, the oversmock was discarded.
2nd Pattern
The 1st Pattern smock design was replaced in 1944 by a second pattern which had buttoning tabs at the cuffs and brass snap fasteners to stow the tail flap on the back of the jacket when not needed. Other detail differences included reduced length and tube shaped rather than tapered sleeves. In order to make it more wind-proof, the tops of woollen socks were often sewn to the cuffs. The half-length zip fastener on this smock was made of brass. The colours of the 2nd pattern also differed from those of the earlier smocks, the base colour varying from a light to a medium olive combination, with overlying brushstrokes of reddish brown and dark olive green. These colours were thought better suited to the North Western European theatre.
Variations

Denisons of either pattern issued to officers had woollen collar linings. By the time of the

airdrops, some officers had had their jackets modified with a full-length zip by their personal tailors, since this was not available on the issue item. Wartime photographs show that some other ranks had their smocks serviced the same way by the unit tailor. The zip was most commonly removed from the 1942 Parachutist's Oversmock, a longer, sleeveless, fully zipped jump-jacket, made of a grey-green denim material that was worn under the parachute harness, but over everything else (including the Denison). This Parachutist's Oversmock also featured a tail flap and its sole intention was to prevent the paratroopers equipment from snagging while emplaned or during a jump. It was to be discarded on landing.
The oversmock had capacious elasticated pockets on the skirt, intended as a safer way to carry

s. These pockets were sometimes removed and added to the Denisons as well.
A sniper's variant of the Denison smock is known, in effect an issue smock with a specialized pocket (approximately 10" x 10") added to the left rear in which could be carried food & water, maps, ammunition, and other small equipment. Modifications were done at the unit level and known examples all vary from one sample to the next.
The Royal Marines used a version which had the half zip replaced with buttons and loops for fastening the opening.
A waterproof Denison in waxed dark green material was also very rarely found during the War.

similar to that of the 'brushstroke' pattern applied to the Denison. The pattern has a base colour of pink with overlying brushstrokes of plum, pale green and dark brown. The Smock, Windproof and trousers were also issued to British troops in Korea during the winter of 1950.
It is sometimes incorrectly referred to as the "SAS Windproof". It was not designed much for parachuting, and lacked a crotch flap, having a drawstring hem instead. The most distinctive point of difference between 'Windproofs' and the Denison smock are that the former are hooded.
Windproof smocks and trousers were worn by French paratroopers in Indochina, and to a lesser extent in Algeria. The French referred to the pattern as "sausage skin".
Variations of the 'Windproof' have been the basic Special Forces smock until the present, with several alternative colours seen over the years – white (or at least natural cotton) for LRDG's desert use; olive green; black; and, in now very rare later issues of the Smock, Windproof, 1963 Pattern, the
DPM introduced in the late 1960s. The current issue Smock, Windproof is in the latest variation of the DPM design.
SOE Jumpsuit
A camouflaged overall garment in a similar camouflage pattern along with a matching cloth helmet were issued to the SOE and allied agents parachuting into occupied Europe and were discarded shortly after descent. The "striptease suit" came with a side shovel pocket, pistol holster, knife pouch on cuff and parallel zips for instant removal of garment. SOE jumpsuits were also issued in white for winter/arctic environments.
Post-war use

and the
Parachute Regiment until the mid-1970s (see below), and changed little from the wartime issue. A full-length brass zip had become standard with no cloth flap to cover it and the knitted cuffs deleted on the 2nd Pattern smock were reintroduced. The base colour of the camouflage pattern was now a lighter khaki shade. The "Newey" press studs changed from brass/copper to nickel-plated versions.
1959 Pattern
The Denison was significantly modified in the 1959 Pattern. This had a higher hem line, and was much less baggy. This was because wearing it over the personal carrying equipment (but under the parachute harness) while parachuting was no longer the practice. The '59 Pattern retained the full length zip and knitted wool cuffs, but the flannel lining of the collar was changed from khaki to light green. The most obvious difference, however, was the change in pattern and colours of the camouflage. The pattern became less random, more defined, with broad, vertical brush-strokes, and greater contrast between the base light khaki and the overprinted tones. The green was much darker than previous versions, and the brown was now chocolate, rather than brick. Where green and brown overlapped, they formed a fourth, darker, olive brown colour.
Replacement

The British Army had officially adopted a
DPM combat uniform for general use in 1972, and a ''Smock, combat, DPM'' was introduced as the general issue jacket of the range. Both the

continued to wear the Denison into the 1990s.
"Although a status symbol in the British Army, the Denison," wrote ex-SAS officer, Barry Gregory, "was windproof but not waterproof and stank after use like a coal-miner's sweat shirt. I used it in extremis as a pillow when sleeping out with sleeping-bag and poncho to keep my head above ground level."
In the UK, the
DPM Smock, Parachutist's began to replace the Denison smock beginning in 1977. The new DPM replacement was not constructed of the Denison's heavyweight twill, but was instead made from the same cotton material as the '68-Pattern combat jacket. However, it was cut like the Denison smock, with smaller Newey press-stud (snap) fastened (but now bellowed) pockets, a full-length zip without buttons down the front, the traditional olive green knitted wool cuffs, and a 'crotch flap' on the outside of the back. With the introduction of the British Army's multi-terrain camouflage pattern (MTP), a version of the "Smock, Parachutist" in that pattern was issued.
The Canadian Airborne Regiment was first issued an olive green replacement for the Denison in the 1950s, and in 1975 a Disruptive Pattern parachute smock entered service, remaining in the inventory until the regiment disbanded in 1995.

to liberate France during WWII, and continued to wear it after the war. The Denison smock was also utilized by most of the soldiers in the French army's
8e Bataillon de Parachutistes de Choc (8e BPC) in Indochina, including while the unit was at Dien Bien Phu; the majority of the smocks worn were in their original configuration, but modifications (particularly to the front and neck openings) were often made by local tailors or unit
riggers.
The British Denison smock also heavily influenced the design of the French jump smock models 1947/51 and 1947/52.

pattern, in which the green and brown brush-strokes were more frequent, but much smaller, on a light greyish green base. Lizard evolved into two main styles: vertical, and horizontal (indicating the general direction of the brushstrokes). Other developments changed the shape of the brushstrokes, using intricate grass-like patterns in the
Rhodesian pattern, or palm frond-like sprays in the Indian pattern. South African Denison Smocks (later replaced by the
Slangvel) were plain sand coloured.
